Here is a hexographer created version of the campaign map that we came up with, as befitting the Dungeon World campaign creation guidelines the map is fairly loose with a lot of blank space left still to explore.
Dark sun Dungeon World – Campaign Map
good stuff how did you get the hex Map – would be useful as a fellow GM
I used the program Hexographer: http://www.hexographer.com/
I've used Hexographer before, its pretty cool. I like the simplicity of the map you have gone for, leaves it clean and with plenty of room to explore.
I've never used Dark Sun as a setting, so will keep my eye on the updates for this one as its a world that always piqued my interest.
